[ntp:questions] NTP - Many Doubt's

Hello All,

I have many doubt's about my equipment. I don't know how it's work.

I have one plate (GPS) in a Rack on my Data Center, follow below some
information:

DIGITAL CLOCK DISTRIBUTOR / SSU
LOCAL PRIMARY REFERENCE
DCD - LPR/C
GTI/C - GPS

This equipment have a cable that begin of a plug DB9 and It have about
9 meter. There is a converter on the end of this cable that convert
the DB9 to DB25.

My firt doubt is about the second cable that begin of the converter.
The end of this cable there are two DB25. My doubt is about the two
DB25. Is it possible 2 box ( Sun - Solaris ) compete using the same
channel? Or It can be wrong?

The second doubt is about the NTP consult. I'd never got a consult on
my equipment, but on the firt time that I connect my box's on the GPS,
after five minutes I got the syncronism, but I'd never got a consult.
Today It isn't work and I dont know what.

Who knows how can I check out if my equipment GPS is working well? Or
if possible two box's compete the same channel? Or only one equipment
is possible to work on this case?

Follow below some commands that i did on my box's:

Can someone show me the light of the end of the tunnel?

I appreciate some help.
